I guess both ways of approaching the subject are true, depending on point of view, but the only really right answer is how each specific person feels about it? If you can take just a moment and honestly answer these few questions, then it is actually super easy to decide which way to go, follow me along and ask yourself these questions and tally up your answers each way.
Are you looking for ultimate precision and accuracy? Want to shoot interesting new calibers? (6mm SLR/ 300 Norma, etc), Want to learn a ton more about the whole shooting discipline? Are you going to be shooting huge volumes of rounds? Have space in your house/garage for a proper gun-reloading room? Are you investing huge dollars and very high end rifles or pistols? Have the time to commit to doing it right? Then you need to reload for sure, no choice about it.
Or are you more of a casual shooter? Don't have time to put the hours into it to learn and read and research and practice to do your craft well, and be safe and not injure yourself? Only have 308s or 30-06s or 223s or other common calibers etc? Then you could easily be just as happy being a box Ammo guy. There are really good Match Ammo choices these days, (example-6.5 Creedmoor, FGMM 308 etc), and you can get it at most any gun store around.
Just be real with yourself about your time and expectations and I think you'll find the answer becomes obvious to you.
As for me personally, I answered yes to all the first questions, and own a number of great high end rifles and wanted to have the best Ammo I could possibly have, so reloading was a no-brainer......but you know what I discovered? I love the reloading! The process speaks to me, and the science, the art, the mystery and challenge of load testing, of making perfect rounds over and over, of perfecting my science and skills, all became very addictive, and now I am not afraid to admit, I am addicted reloading almost as much as I love shooting!
Ask any serious hand loader if they like it, and 95% of them will say they love doing it too. Now for the caveat.....it's an initial steep learning curve, you can spend thousands and thousands on gear chasing that perfect ammo load, and it takes up more room in your house then you might think, but for me, and most reloaders, it's totally worth it.
Oh.....and the fancy reloading gear you can buy!!! Talk about man cave toys! Chargemasters/ Dillon 1050s/ Benchsource Annealers...and so on. Not to worry if those names mean nothing to you just yet....any serious reloader worth his salt, is salivating reading that last sentence. And there is no better feeling then opening that Canpar brown box from Budget or X-reload and looking at a perfect piece of Norma or Lapua brass and imagining the sub-MOA accuracy you hold in your hands!
I also feel that any serious or even semi-serious shooter or gun enthusiast who chooses not to reload is missing half the fun of being a "gun guy"!
Just my thoughts for you to mull over, and YMMV....
